To @U whom t may concern:

Be it known that I, CaniJ OTTO MLLER, architect, a 'subject of the GermanEniperor, and resident oi Blankenese, near Hamburg, Germany, have invented certain new and useful Improvements in Shoes'for Wooden Poles, ot which the'iollovring is a specification.

Wooden poles as are lanted in theA earth in the open and should e especielljr applicable to postsand poles for supporting overhead electrical equipment; but the shoe can also' iind application ,for other purposes, such as to protect theiootof the growth, and the like.

in the present case'the shoe consists of an iron tube. closed at the bottoni and provided With devices for an active circulation of air :and for theeasy insertion, protection, and re-v placement of thevpoles. Moreover, the shoe .is so contrived that' rain-Water and the like is preventediroin entering, and the breaking 5 improvement of shoes 'ot' this kind brought about by a special construction of the jacket surroundingr the upper part of thetube.

ri`he improvement consists in this, that-- the upper edge ofthe outer jacket is bent obliqueiytoivard the inside. Thisslanting portion of thel jacket tits into a' groove,

-ni'itched out at a.' suitable' height round the pole. ln this way it is brougintabout,l

firstly, that Vthe pole is gripped and held firm when the jaeketis' screwed up; scc` ondly, that the upper` part of the tube is strengthened bynieans of th jacket, and the eventual lateral prrs'sureof. the ole is supported directly on. the jacket 5 thirdly, that a perfect safeguard against the penetration of;
